ASTM A537 Class 1 Pressure Vessel Steel Plate

ASTM A537 Class 1 carbon steel plates are engineered to be used in pressure vessel applications.

Applications of ASTM A537 Class 1 Carbon Steel Plate  

The material is a normalized steel which is heat treated and as a consequence displays greater yield and tensile strength than the more standard ASTM A516 grades. The steel is ideal for use in pressurized service both in boilers and pressure vessels and we supplies A537 Class 1 plates to the world’s leading fabricators who in turn serve the Oil, Gas and Petrochemical industry.
